Office 365 groups expiration is now in public preview

Today we’re announcing the public preview of Office 365 groups expiration for Azure Active Directory Premium customers. You can now manage the lifecycle of Office 365 groups, by setting an expiration duration for any group you choose. Once this is set, owners will be asked to renew their group as they come close to expiry if they want to continue to use them. Any group that is not renewed will be deleted.

Office 365 groups expiration can be configured from the Azure Active Directory portal, as well as programmatically via Azure Active Directory PowerShell. You can also create a policy that applies to all the groups in your tenant.

30 days prior to the expiration of a group, renewal notifications are sent out by email to the owners of the group, from which they can renew their group with a single click. If the owners don’t renew the group within the required timeframe, the group expires, and is deleted.
